Summary
| Description |
English: Timelapse of near-Earth asteroid/Earth quasi-satellite 2004 GU9 moving across the sky in images taken by the Canada-France-Hawaii Telescope (CFHT) on 9 February 2007. Each frame is a 300-second exposure in the r-band filter, taken in 6-minute intervals. Due to the asteroid's rapid motion and long exposure time of each image, the asteroid appears streaked along its direction of motion. The white specks and pixels that sporadically appear are image artifacts caused by cosmic rays. The image is oriented North up and East left. |
